9 lis 2023 · The fight or flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival. It prepares your body to either confront or flee from the threat by triggering changes like increased heart rate, quickened breathing, and heightened alertness.
The scripts are intended to help you as you begin to talk to children and youth about freeze, flight and fight. As you become more comfortable you will create your own script adapting to the specific needs and abilities of the child or youth with whom you are working.
Aviation Physiology deals with the physical and mental effects of flight on air crew personnel and passengers. Study of this booklet will familiarize you with some of the physiological problems of flight, and will instruct you in the use of some of the devices that aviation physiologists and others have developed to assist in human compensation ...
An aircraft in straight and level, constant velocity flight is acted upon by four forces: lift, weight, thrust, and drag. The opposing forces balance each other; in the vertical direction, lift opposes weight, in the horizontal direction, thrust opposes drag.
1-1 When pressure is applied to the airplane controls, one or more of the basic forces changes in magnitude and becomes greater than the opposing force, causing the airplane to accelerate or move in the direction of the applied force.
Flight – Understanding Air Pressure and Air Flow. Student Objectives. An increased speed of airflow over a surface results in a decrease in air pressure over that surface. Air moves faster over a cambered, or arched, surface than over a flat surface. Together, these two facts explain how an airplane lifts into the air and stays in the air.
The weight of air above a given area on Earth’s surface is called atmospheric pressure. It is an important factor influencing Earth’s weather and climate. Atmospheric pressure can be measured with an instrument called a barometer and thus is also known as barometric pressure.
